Problems solved by technology

[0003] At present, known tower cranes and winch hooks all hang the hooks directly on the shackles of bricks, stones, and material boxes or on the mine car shackles. Larger swings are the same as the principle of the balance wheel in physics, especially at the track joint of the mine winch. If the installation is uneven and the coal mine car swings back and forth, there will be hook decoupling accidents from time to time. Loss of materials, damage to the mine car, or serious accidents caused by the mine car falling down and causing personal injury or death

Embodiment Construction

[0019] 1. Design, production and installation of circular or circular chains: The chains commonly used in machinery include welded circular chains, figure 8 chains, hook chains, etc. Due to the welded circular chain (5), the structure is simple, convenient to manufacture, and economical , Suitable for heavy load conditions. made as figure 2 , the endless chain (5) in Fig. 3, chain size: diameter d is 7mm, and pitch t is 21, and width B is 24, and load test is 0.8 tons, and load destruction is 1.6 tons, and material selects A2 or A3 for use, adopts, selects for use The welded endless chain (5) is more than sufficient for the lifting load of tower cranes and mine cars.

[0020] 2. There are two types of ring chains: rough and refined. You can choose either of the two. Since the number of links used is not large and the price is cheap, refined ones can be used and purchased in the market according to design requirements.

[0021] 3. The connection between the ring or circular ...

Abstract

The invention relates to a hoist hook device for a tower crane and a winch, which is the hoist hook device for a construction tower crane and a mine winch to hoist materials, ores and the like. In the hoist hook device, a plurality of nodes of an annular or circular chain are connected to the hook head of a hoist hook, and the other end of the annular or circular chain is connected with a pulley or a wire rope. The hoist hook device has a simple structure, is convenient to manufacture, is economical and is applicable to large-load conditions. The annular chain has higher flexibility and has a buffer function when the hoist hook device is swung and especially drastically swung, so that personal casualty accidents caused by unhooking are prevented and avoided. In the hoist hook device, a small number of nodes of the annular chain are used, both rough chains and fine chains can be use, and the safety problem can be solved at low cost.

Description

Technical field [0001] The invention relates to a hook device for a tower crane and a winch. [0002] The tower crane and winch hook device is a hook device for building tower cranes and mine winches to lift materials and ores. It is convenient and fast, especially safe, and can prevent and avoid decoupling personal casualties during lifting. Background technique [0003] At present, known tower cranes and winch hooks all hang the hooks directly on the shackles of bricks, stones, and material boxes or on the mine car shackles. Larger swings are the same as the principle of the balance wheel in physics, especially at the track joint of the mine winch. If the installation is uneven and the coal mine car swings back and forth, there will be hook decoupling accidents from time to time. Loss of material, damage mine car, serious then mine car falls to take place personal casualty accident. Contents of the invention [0004] The purpose of the present invention is to provide a...
